[Billy Joel] hired a bodyguard to protect his daughter and contacted [Paul] McCartney, who recommended a Europe-based private-security firm not bound by the same legal restrictions as the police, [Post] sources said.

McCartney's people found the stalker in Austin, Minn.

She weirdly told law enforcement that the rape and murder she allegedly threatened in the messages were not things she wanted to do "during this life," according to court records.

Finley, who spent a few months in a mental institution in 2010, remained hopeful that Alexa Ray would not "object to meeting with her."

In January, an Austin TV report said Finley used an alias and computers at Riverland Community College when contacting Joel (Joel isn't mentioned by name in the KAAL report).

Finley was charged with felony stalking. She posted bail and was released from custody following her January arrest.
